I need a Corsair 8gb 3200mhz ram. Every website showing Same model just like Corsair 8Gb 3200mhz LPX. But Every website showing different different Tested latency, Just Like one website showing Tested latency 15-17-17-35. Another Website showing 16-20-20-38. Now i am confused. Which one i will buy???
Buy the 15-17-17-35 one, the lower the numbers the better. However this does not work when comparing between speeds, for example: If you see a 3600MHz CL 18-20-20-38, this will be faster than a 3200MHz CL 16-18-18-36 because the clock speed is 400MHz faster.
Those numbers show the speed in nanoseconds the data in the ram is read between intervals. So for the 15-17-17-35, the first number shows 15 nano seconds between reads. Much better value than 16. Same goes for the 17 and 20 values. This is called, CAS Latency, or CL for short.
